Description

Technical Field

[0001] The utility model belongs to the technical field of Chinese medicine preparation, and particularly relates to solid-liquid separation equipment for Chinese herbal medicine extracts. Background Art

[0002] Chinese herbal medicine extracts are obtained by extracting, separating and processing Chinese herbal medicines or Chinese herbal medicine compounds using advanced technology. They have a relatively clear material basis for efficacy and are a kind of Chinese herbal medicine product with strict quality standards. They are a new product form in the international natural medicine and health care product market. They are the main raw material for herbal medicine preparations and can be widely used in natural health products. Commonly used processing methods for Chinese herbal medicines include water processing, fire processing and water and goods processing. After processing, the Chinese herbal medicines need to filter out the drug residues before they can be taken.

[0003] In contrast, a Chinese patent with announcement number CN217729760U discloses a solid-liquid separation device for a Chinese medicinal material extract, comprising a screw pressing mechanism, wherein the screw pressing mechanism comprises a frame, a screen, a screw shaft, a lower hopper, and a discharge assembly located in the lower hopper, wherein the screen is fixed on the frame, the screw shaft passes through the screen, the lower hopper, and the discharge assembly in sequence, and is rotatably arranged on the frame, and a discharge port is formed between one of the inner side walls of the lower hopper and the discharge assembly; a cutting assembly, which comprises a rotating member rotatably arranged on the lower hopper and a plurality of cutting tools located on the rotating member, and the cutting tools are arranged toward the discharge port.

[0004] However, the above patent has a single solid-liquid separation method for the medicinal residue, which only involves one pressing operation. The solid-liquid separation of the medicinal residue is not thorough and the medicinal residue is prone to blockage of the discharge port. Therefore, a new device needs to be designed.
